Solanum, probably S. dulcamara

Thanks a lot, Purpleinopp! I googled it and there are a lot of them, wow. Some leaves don't look like mine, but probably most of those are not weeds from warmer zones. I was surprised it's related to potato.
Anyway, wiki says that S. dulcamara (bittersweet nightshade) is an invasive weed (yes) and that it's poisonois! I noticed several times that after weeding my skin itches, probably because of this.
My next weed looks kinda like that, maybe they are related, I'll post a pic.

You're welcome, and oh yeah, you're right. I forgot the lovely rash it used to give me, luckily I haven't had to deal with this one for a long time. Not as bad as poison ivy, more like juniper burn, at least it was for me. Really is a pretty weed though I prefer to see it in pictures or someone else's yard.

I'd prefer to see it in pictures too :)) So it does give you a rash, doesn't it. I'll try to be careful next time. Thanks again!
